Abstract

Les modes de réalisation de la présente invention concernent un procédé de rétroaction de demande de répétition automatique (HARQ). Ledit procédé comprend les étapes suivantes : une station de base envoie des premières informations d'instruction, les premières informations d'instruction étant utilisées afin d'ordonner à un terminal d'effectuer une rétroaction HARQ ; la station de base envoie des secondes informations d'instruction, les secondes informations d'instruction comprenant des secondes informations de temps afin d'ordonner au terminal d'effectuer une rétroaction HARQ ; et la station de base reçoit des informations de rétroaction HARQ du terminal. Éventuellement, la station de base peut envoyer les premières informations d'instruction lors d'un premier temps d'occupation de canal (COT) et envoyer les secondes informations d'instruction lors d'un second COT. La présente invention ordonne, au moyen d'une approche de planification en deux étapes, une rétroaction HARQ à exécuter, et peut améliorer la probabilité d'accès d'un canal de terminal, et également assurer efficacement la transmission de la rétroaction HARQ.
